1. A method of controlling a vehicle comprising:
providing an axle assembly that is operatively connected to an electrical machine that is configured to provide torque to a vehicle wheel and a one-pedal driving system that has a pedal that controls torque provided by the electrical machine;
determining an operating region based on vehicle speed and a position of the pedal; and
controlling torque that is provided by the electrical machine based on the operating region, wherein controlling torque that is provided by the electrical machine includes determining a scaled propulsion command when the vehicle is operating in a propulsion region and providing propulsion torque to the vehicle wheel with the electrical machine based on the scaled propulsion command, and wherein the scaled propulsion command is determined by scaling a detected position of the pedal with respect to a propulsion torque vector that is based on the vehicle speed and that extends from a coast region to a maximum position of the pedal.
